6 Claims.

Wringers andthe like are usually provided with yielding pressure means for the rolls and devices for adjusting this pressure. The present invention is designed to improve the mechanism for adjusting the pressure. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:

Fig. 1 shows a front elevation of the wringer partly in section.

Fig. 2 an enlarged section on the line 2-2 in Fig. 1.

Fig. 3 a perspective view of a guide plate for the adjusting mechanism.

Fig. 4 an adjusting plate for the adjusting mechanism.

I marks a base of the wringer. This is trough shaped and'has a discharge opening 2 at its opening. 3-3 mark thel stiles of the wringer frame, these being secured to the base. A top bar 4 is arranged over the stiles. 5 and 6 vmark the rolls of the wringer. These have the shafts 1 and 8 respectively. Bearings shaft 1, these being anchored in the lower part of the stiles. Bearings I0 are provided for the shaft 8. These bearings are slidingly mountedin the stiles. A spring II rests `on the upper bearings and exerts pressure from the top bar. One of the stiles has shoulders I2 struck up in it which engage shoulders I3 in one end of the top bar.

A resetting and release lever I4 is hinged at A link I6 (see dotted line) is pivotally connected by pin I1 with the lever I4 and is pivotally connected with ears I8 extending from the face of the stile by a'pin I9. The lever and link form a toggle which, when the lever is on the stiles, is moved to position against the stile, draws down the top bar,- and holds it in set position. A handle Illa is arranged on the lever I4 by which it may be easily operated for release.

'I'he adjusting mechanism comprises the U- shaped guide plate 20, the .upper end oi.' this plate being flanged and secured to the top bar by rivets 2 I The side walls of this guide plate are provided with vertical slots 22. A clip 23 is'arranged on the spring. It has a depression 24 which extends into a depression 25 in the spring. The clip has downwardly extending sides. A pin 26 extends through perforations 21 in the downwardly extending sides and locks thev clip with the spring. The pin has the head 28 atlone 9 are provided for the end which engages the face of the guide plate 20 and a washer 29 at the opposite end secured by heading the pin at 30, the washer engaging the face of the guide plate 20. Through this pin, the head and Washer, the vertical travel of the spring is controlled, the center of the spring be-v ing free to move up and down but is maintainedv in its central position.

The adjustingV device comprises an adjusting plate 3Iwhich is U-shaped and has a slight extension 32 on its top which extends through a slot 33 in the top bar. Ahandle 35 is secured by screw 34 in the extension 32. By means of this handle the adjusting device may be moved longitudinally in the slot. The adjusting device 3| is in the form of a U-shaped plate which plate straddles the spring II and the clip 23. The sides of this plate is slotted at 36 and the upper edge of the slot has stepped surfaces 31-31and these diierent surfaces may be interposed between the top bar and the pin 26 so as to change or vary the spacing between the spring and the top bar, a greater spacing providing greater pressure'for the spring and a lesser spacing a lesser pressure for the spring. As shown, this providesv three adjustments. When, therefore, it is dev sired to change the pressure the top bar is loosened by the operation of the lever I4 and the adjusting device moved to the center on the ends of the slot 33 bringing either the end stepped surfaces or the middle surface' into position to give the desired adjustment.

In order that the adjustment may be retained for the purpose of release rather than adjustment, the lower edge of the slot 36 has notches 38 which are arranged opposite the stepped surfaces 31. As the top bar is released, the spring and with it the pin 26 drops down by gravity into the notches 38 and is thus located in these notches sufliciently to maintain the adjustment," but the adjusting device maybe moved, the spring rising over the projections between the notches as the device is moved. In other Words, this mechanism forms a yielding gravity held positioning arrangement that yieldingly holds the adjust-A ment when the top bar is released but permits the adjustment through a sufiicient force on the adjusting member 35.

What I claim asnew is:

l. In a Wringer or the like having a frame; and rolls mounted in the frame; the combination therewith of a top bar on the frame; a pressure mechanism f or'the rolls comprising a pressure means and a pressure adjusting device mounted on the top bar and movable horizontally and 2 reetumeerly with relation thereto, seid device mtcrposing as it is moved stepped spacing surfaces varying the spacing of the pressure meam from the top bar.

2. In a wringer or the like having a frame;

and rolls mounted in the frame; the combination therewith of a top bar on the frame. said top bar being slotted; a pressure means for the rolls; a pressure adjusting device having a part extending through the slot and slidably adjustable along the slot, said pressure device interposing as it is moved spacing surfaces varying the spacing of the pressure means from the top bar.

3. In a wringer'or the like having a frame; and rolls mounted in the frame; the combination therewith of a top bar on thevframe, said top bar having a slot; a pressure spring exerting yielding pressure on the rolls; a pressure adjusting device for the spring comprising a U-shaped plate straddling the spring and having varying spacing surfaces on the sides of the plate; anoperating member extending through the slot for moving the plate and adjusting the surfaces; and means on the spring engaging the surface 4. In a wringer or the like having 'a frame; and rolls mounted in the frame; the combination therewithof a top bar on the frame,

' tioned slots and adapted to engage the stepped surfaces and the notches; and a member extending from the adjusting device through the ilrst mentioned slot for operating the adjusting device. 4, 5. In a wringer or the like having a trame; and

Vrolls mounted in the frame; the combination therewith of a top bar on the frame, said top bar having a slot and being releasable relative to the frame; a pressure spring exerting yielding pressure on the rolls; a pressure adjusting device for vthe spring comprising a U-shaped plate straddling the spring and having varying spacing surfaces on thesides oi the plate; an operating member extending through the slot for moving the plate and adjusting the surfaces; means on the spring engaging the surfaces; and a vertical guide for the spring.

6. In a wringer or the like having 'a frame; and rolls mounted in the frame; the combination therewith of a top bar on the frame, said top bar having a slot and being reieasabie relative to the frame; a pressure spring exerting yielding pres sure onl the rolls; apressure adjusting device for lthe spring comprising a U-shaped plate stradsaid top bar having a slot and being releas'able v relative to the frame; a pressure spring exerting yieldingI pressure on the rolls; a pressure adjusting device for the. spring comprising a U-shaped plate straddling the spring and having `slots in lits sides, the upper edges oi' the last mentioned slots providing stepped surfaces, and the lower vedges of the lastV mentioned slots providing notches opposite the stepped surfaces; a member on the spring extending through the last mendling the spring and having slots in its sides, the

upper 'edges of the last mentioned 'slots provid-A for the spring.
